BED-SPRING.

SPECIFICATION forming part of Letters Patent N0. 554,822, dated February 18, 1896. Application filed Aiigust 21, 1 895. erial No. 560,044. (No model.)

To all whom it may concern:

Be it known that I ,WILLIAM H. IvENs, J r. of Trenton, in the county of Mercer and- State of New Jersey, have invented an Improved Bed-Spring, of which the following is a specification.

This invention relates generally to bed-bottoms, and particularly to that class thereof known as spring bed-bottoms; and the object of my invention is to provide a reversible set of springs whichcan be used upon either side, and a further object is to construct said springs in book formthat is, composed of two hinged sections, adapted to fall one upon the otherwhereby the springs can be placed upon the slats more conveniently and with less liability to scratch the head and foot boards of the bedstead. The main object, however, of my invention is to construct the spring bed-bottom in such a manner that an elastic bearing-surface will be provided which will be exceedingly elastic and yielding in all positions and at the same time be sufficiently rigid to maintain all of the springs in their proper position at all times.

My invention consists in certain details of construction and combination of parts, all of which will be fully described hereinafter, and then pointed out in the claim.

In the drawings forming a part of this specification, Figure 1 is a View showing my improved form of bed-bottom. Fig. 2 is a top plan View of a portion thereof. Fig. 3 is a detail perspective View of a portion, and Fig. 4c is an enlarged diagrammatic view.

In carrying out my invention, I employ a series of upright springs A, made in the form of a spiral or helix, the outer coils of said springs being larger than the inner coils, as clearly shown. These upright springs are arranged in regular order or series, and in order to hold the same in their proper position I employ a series of intertwining coiled wires B, said wires being extended in series across the face of the bed-bottom in either a longitudinal transverse or diagonal direction, each wire B being coiled or intertwined around the outer coils of the adjacent series of upright springs A. It will be noticed, however, that these springs B run in parallel series in both directions and intersect each other, as at O,but aside from this there is no connection between the wires B. In order to unite these wires B, and thus produce an unbroken bearing-surface, I employ the coiled cables D, said cables being passed between each parallel series or wires Band intertwined therewith to connect the wires B together and thus unite one series of upright springs with the next adjacent series and provide a spring bed-bottom having an unbroken elastic bearing-surface strengthened along the lines of the coiled cables. These cables are composed of a plurality of Wires, preferably four in number, and these add great strength to the bed-bottom, holding the upright springs securely in their proper position and yet forming sufficient elastic movement to insure ease and comfort.

Where the coiled cables cross each other they are intertwiste'd in such a manner as to avoid any raised or depressed portions, and the smoothsurface is thus produced.

The border E surrounds the set of springs as shown, said border being composed of a coiled cable similar to the cables D.

In making the bed in sections each section is constructed as before describedthat is, each section consists of a series of upright springs, the intertwined springs, and the connecting-cables, all contained within the coiled cable proper, and in order to unite the sections I employ the parallel rods F F, which pass through the coils of the adjacent borders of the sections, said rods being connected by 1neans of hinged clips G bent upon said rods,

as at g, and in order to prevent any longitudinal movement of said clips along the rods I bend said rods in such a manner as. to provide recesses or offset portions f, in which the clips are located. By means of this construction it will be seen that the two sections are securely united, that one section can be readily fitted upon the other, and that at the point of junction a rigid connection is attained, which will prevent one section falling below the other.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I provide an exceedingly simple, eflicient and durable spring bed-bottom, one which will maintain its shape under all conditions, and one which will be exceedingly easy and comfortable.

Having" thus described my invention, what I claim, and desire to secure by Letters "atout, is

An improved bed-spring formed of two sections hinged together, each section consisting of a series of upright coil'springs arranged at regular intervals, a series of horizontal coilsprings connected to the upper and lower coils of the vertical springs, extending across both the upper and lower faces of the bedbottom in parallel order, and independent of each other, each horizontal coil-spring consisting of a single wire, and the series of coiled cables extending between the parallel coilsprings intertwined therewith, and conneeting them, whereby an unbroken elastic surface is produced, said coiled cables being composed of a plurality of wires, the coiledeable borders for the upper and lower ed gcs of each section, the hinged bars F, and the clips G, said clips being located in the re cessed or bent portions of the hinged bars, substantially as shown and described.

In testimony whereof I aflix my signature in the presence of two witnesses.
